Hey second resonance does occur at the third harmonic but it is still the second mode of vibration( harmonic is not necessarily same as the mode of vibration)
I got this reference in a book:
Second normal mode of vibration : n2 = v/λ2 = 3v/4L = 3n1
(pipe closed at one end)
I...
Ok I get it. Pipe closed at one end has only odd harmonics. And the second resonance actually occurs at the third harmonic(i.e. the third mode of vibration).Thanks :smile: :smile:
Homework Statement
A cyclindrical pipe of length 29.5 cm closed at one end resonates with a tuning fork of frequency 864 Hz. Then mode of vibration of air in the pipe is(Velocity of sound in air=340m/s):
The attempt at a solution
V=Velocity, n=Frequency
If l1 is the first resonating...
In alcohols, the negative charge on 'Oxygen atom' increases due to '+I effect' of alkyl groups. While in acids, the '+I effect' of alkyl groups decreases the positive charge on the 'Carbon atom'.
In the first case the +I effect makes it easier to break the C-O bond while in the second case...
ok, I solved the combinations and I got 3/4 R.
but what if the circuit is not symmetrical..that is if we have to find the equivalent resistance between A and B?
hey can anybody please tell me how to solve this circuit?? :confused:
I tried this sum out but I can't understand which points are symmetrical and have same potential..or how the current is distributed
